Since I got headers, I obviously added the tune, but I'm sure the power gains were mostly hardware driven and not much tune related.

I think this is simply a matter of apples and oranges dynos being used to support gains that aren't really there. Like Vic said, only way to verify for sure is to take it to the track/street for a roll-on comparison with a stock P31.

Anyone want do a roll with me with their stock P31?

Rode in a 2012 P31 with a Renntech tune today.... Got to drive it later as well..

I can actually feel a difference! Felt quite a bit faster (More torque). At least that's what my *** dyno says.

If it wasn't for me being scared about warranty I'd do an EC tune.

Just got an OE Tuning handheld for that reason, flash back to stock for trips to the dealer if need be.

NESHO, did you handheld flash it? or did they crack it open?

I have a feeling they cracked it open as the handhelds dont seem to make any power gains on the p31's.

Weird, cause you posted about 5 times in a thread with a Dyno graph of a BS making way more power than what mb claims.

Cheers!

Oh Canada!

Good for you buddy!

My first question is: WTH? Lol where in Vancouver are you planning on driving it that fast? Please make sure to race Michael Buble (he has the same car as us) if he pulls up next to ya. I believe his C63 is still stock? Oh and I'm from Victoria & Vancouver... Lol

So, I jumped out of bed to write you at some ungodly hour of the morning because I too have the P31 PP on my 2012 C63. After 8 months of research and reading these forums, I finally decided to move forward with Weistec!

Ready for this boys?

Max Horse Power @ The Wheel: 454.76
Max Torque: 403.50

So If any one in a stock C63 w/P31 wants to come to shift sector next weekend, I will be there. Look for the sexy red head in the diamond white c63... Like y'all said, lets put this to the test and I'll gladly post my GoPro Camera Footage for review. I'm just there to have fun! God forbid if anyone gets beat by a girl!

Also, if their are any fellow lady drivers reading this post, shoot me a PM with any questions! Cheers!

I say this because of course the B.S. is 510HP, & has the same engine as P31...except for ECU.....I was just thinking that as B.S. is "the ultimate", it would probably have pretty much the "maximum" for this spec engine, so an increase to around 510 at the crank, would be about "it"?
Cheers, Pickles.
Well said, Pickles! I agree with ya on this one.

What a waste of perfectly good alcohol Vic!! I remember when I had my first beer!

Beer-Thirty? That good eh?

Your "Black Series" is "Blacked Out" right? I think some dudes call that "murdered?" Makes no sense to a chick... Oh so your car is big & black?! Your car has a new nickname: "Mandingo." lol. Welcome to my car world.

Hey Vic, you may as well come out to play! Jimmy is brining his Caucasian Mandingo Series! You may as well take his left overs and race the losers. That'll really **** off your BMW buddies though... No allegiance!

Out of curiosity, were you both(NESHO & LK) using 94 octane from Sunoco or Petro Canada?

BTW, nice one LK with the "Mandingo" reference
